it's on the spare 325iC, it had it then and it has it now, she sat for about 8 months.
- today did Continental t.belt, tensioner, spring and WP.
- ran it with and without a/c, wp/alt, p/s.
- also ran it with and without lower t.belt cover as it had some old traces of rubbing.
- also checked distributor and rotor, no binding there.
whine still there and not sure why, sounds like from forward side of engine.
heard about injectors or fuel pump whine, could that be it ?
Pull the distribuor cap rear dust cup and look for contact. Take off the fan clutch and try running with out it. The timming belt could also cause this noise if too tight. Also the tensioner could be NFG, I've bought new ones and they made noise but this is rare.
Try this and let me know. But I think the timing belt is too tight...
haha, scared the crap outa my kid... then agian i had it loud... lol

Thanks for all the great advise.
Today de-tentioned T.Belt but it was not the problem used:
So, used a piece of vacum hose and found a leak between thermostat housing and head, that little gasket it's cracked in 3 pieces
(see enclosed pic), repaired it with some gasket glue and wistle went away for a little while,
so picked a replacement and will install it tomorrow., that should fix it.
If not it, then injector # 1 "O Ring" it's all dryed up.
- Replacing thermostat housing gasket did quiet it down but still whistle a bit, just not as loud.
- So, proved again with a vacuum hose, still can hear it leak in frontal area, near 1st injector, sprayed area with Disc Brake cleaner and idle roused, so swapped all of the O Rings on manifold as well as on Fuel Rail side.
Engine idles a lot better, whistle diminished even more, now it's somewhat faint and you can actually hear suction sound of vacuum leak.
- Proved around yet again and yeap, vacuum leak persists between thermostat housing and first stud of intake manifold, so, next step will be intake manifold gaskets.
Did find 2 loose screws on fuel rail as well as not tight enough nuts on forward side of intake manifold., some of the O Rings on Fuel Rail had splits and one on actual injector was missing a small piece., so, some progress was made after all.
